Description: 1Hz-50 Crystal Oscillator Tester Meter Digital LED 1Hz ~50 Five-digit resolution (eg display X. x kHz X. x or xx. ) Measure amplitude up to 30 V 4-40 Meters can measure passive crystals Automatic range switching with different gate times Optional addition or subtraction of a offset (programmable) Low component count: a PIC 16F628, 5-segment LED displays, a 20 crystal and a few resistors Optional (configurable) power saving mode that automatically does not change the display off when the substantially within 15 seconds USB 5V or DC5-12V power supply can be used Specification: Welding installation considerations, these steps: The components are welded on the back of the board (including good resistance capacitance microcontroller screen printing side), from low to high, the first principle, namely low welding components, such as crystal, capacitor, resistor, diode. The welding microcontroller header, and then welding, triode, knob, a power outlet. The back with a side cutter to short the pins as far as possible Debugging steps: After completion of welding IC PIC16F628 microcontroller, note the direction of IC, the insert can damage the chip! Check the against, such anti take timely correction. After the check, the electricity, the fourth digital tube display 0. said the installation was successful! Using the step of: Before measuring , please switch J1 cap. blue terminals for the IN for input, GND GND for input amplitude does not exceed 30 V, otherwise the meter damage. Before measuring crystal please switch the J1 cap in JP1 insert 4 m to 40 m crystals can measure the crystal Note: This is unassembled DIY Kits Package Includes: 1 Piece Meter DIY kit
